Thank God DIN 49441 for European recessed plugs.

In case anyone wasn’t sure what would happen - this basically short circuits your outlet and causes a lot of big sparks to come bursting out of the outlet. Depending on house your house is wired any combination of the outlet, nearby appliances, or everything could suddenly lose power. Learned this lesson when I was 13, just good that I didn’t die.

What a shockingly simple solution.
